Purpose:

Our primary aim is to assess the feasibility of initiating treatment in the ED with extended-release naltrexone (XR-NTX) plus care management (CM) vs. standard care and continuing care in cooperation with clinic providers as well as how best to assess outcomes. Secondarily, the investigators will explore its effect on various health outcomes (healthcare utilization and engagement, expenditures, drinking and consequences, quality of life) as well as the association of patient-level characteristics (e.g. sex, race, baseline drinking, health and psychosocial factors, mu opioid receptor genotype) with effectiveness. Determining both how to implement XR-NTX+CM and rigorously test its effects in the ED (phase 1) is essential before planning a large-scale effectiveness trial (phase 2).


Study summary:

Aim #1: To conduct a feasibility and acceptability study of XR-NTX+CM treatment in alcohol dependent patients with frequent ED use. Hypothesis: Enrollment of a limited number of subjects will allow identification of optimal processes for a definitive trial. Aim #2: To conduct an analysis of the effect of this intervention on healthcare utilization and engagement, drinking outcomes, quality of life, and consequences of drinking (initial analysis will be exploratory). Hypothesis: Measuring changes in healthcare utilization, drinking metrics, and indicators of quality of life and consequences will provide preliminary data on intervention effect size on various outcomes of interest to inform the second phase, definitive trial. Aim #3: To identify patient-level characteristics associated with effectiveness. Hypothesis: Exploratory analysis of patient and system-level characteristics possibly associated with effectiveness will inform treatment choice to maximize the probability of successful outcome. Factors assessed will include data collected in ongoing investigations of pharmacotherapy for alcohol dependence, including mu opioid receptor (OPRM1) genotypes, to facilitate comparison across study populations and settings. This a phase IV, randomized, open-label, non-placebo-controlled, single-center study of the feasibility, acceptability, and effect of initiating treatment in the ED with extended-release naltrexone 380mg intramuscular injection compared to standard care in subjects with severe alcohol use disorders (i.e. alcohol dependence) and frequent emergency department use. In the first two years, we will finalize study preparations, recruit and randomize 50 subjects for the pilot phase of this study. The duration of each subject's participation will be 12 months. Thereafter, in the second phase of study, we will enroll an additional 250 subjects (for a total of 300 subjects) to address remaining feasibility and acceptability concerns and test effects. The study investigators (PI and RA) will collect process data, including barriers and facilitators encountered in the completion of all study procedures. For the following study procedures, study investigators (the PI and RAs) will enter data directly into New York University Langone Medical Center (NYULMC) internal REDCap system for use on portable tablet computers. Synopsis of Study Procedures: The following study procedures are described in greater detail elsewhere in this protocol. Patients will be prescreened for potential eligibility and added to an automated alert system linked to ED registration by Bellevue Care Managers as part of an ongoing quality improvement initiative. When a potentially eligible patient presents to the ED, an automated page will be delivered to the study PI and Bellevue ED social work and care management staff, prompting consultation and potential referral of the patient to study investigators (PI/RA) for recruitment (See 4.3 Subject Recruitment and Screening). ED medical providers (inclusive of ED physicians, nurses, social workers, and care managers) will notify study investigators (PI/RA) when potentially eligible patients are present in the ED. The medical provider will introduce the PI/RA to clinically sober and medically stable patients who have given their permission to be approached. The PI/RA will describe the study, confirm capacity to consent using the University of California San Diego Brief Assessment of Capacity to Consent to Research (UBACC), and obtain written informed consent. The PI/RA will confirm eligibility by performing a chart and laboratory review (liver enzymes, pregnancy, urine drug screen), history and examination, and diagnostic interview to confirm alcohol dependence and assess for opioid use and chronic pain. The PI/RA will conduct research intake assessments and interview and collect blood for biomarker (5mL) and genetic (10mL) analyses. The PI/RA will randomize subjects to intervention (XR-NTX+CM) or Standard Care using a random number generator with randomly permuted blocks with allocations contained within opaque sealed envelopes. 1. For subjects randomized to the Intervention Arm, the PI/RA will confirm the drug screen is negative for opioids prior to administering XR-NTX 380mg as an intramuscular gluteal injection. The PI/RA will facilitate a person-centered, harm-reduction-based motivational interview, , and psychosocial assessment/interview to inform subjects' care-management plans. Subjects will receive a one-week referral to Bellevue ambulatory care for initial Alcohol-Medical Management (MM) and will also be scheduled every 4 weeks (after most recent XR-NTX injection) for MM and XR-NTX injections. When possible, participants who miss MM-injection visits will be navigated to clinic upon their next ED presentation and/or may receive MM and XR-NTX in the ED. XR-NTX will be administered by the PI or a provider (physician, physician assistant, or registered nurse) who is trained in the administration of XR-NTX. The schedule for MM-Injection visits is weeks 4, 8, 12, 16, 20, and 24. Participants may be offered to continue XR-NTX treatment through this study for as many has 12 injections in total as we explore the feasibility, acceptability and potential benefits of extending treatment duration to 12 months. The schedule for potential additional MM-Injection visits is weeks 28, 32, 36, 40, and 44. Research assessment visits will occur at weeks 12, 24, and 48 and may be conducted up to 28 days prior to- or 90 days after- date in which research visits are due. During research visits, the PI/RA will repeat the assessments that were conducted at the initial enrollment visit plus adverse events and participant satisfaction and we will collect a 5mL blood sample to examine alcohol consumption biomarkers. Subject participation ends after the week-48 research visit. 2. For subjects randomized to the Standard care arm, the PI/RA will provide referral to Bellevue ambulatory care for MM without further intervention. Research assessment visits will occur at weeks 12, 24, and 48 and may be conducted up to 28 days prior to- or 90 days after- date in which research visits are due. During research visits, the PI/RA will repeat the assessments that were conducted at the initial enrollment visit plus adverse events and participant satisfaction and we will collect a 5mL blood sample to examine alcohol consumption biomarkers. Subject participation ends after the week-48 research visit.
